Analysis on Effect of Tensile Force on the Fundamental Frequency of Coupled Vibrations of a Straight Rotating Slender Beam Linearly Varying Channel Cross Section Under Aerodynamic Couplings

Investigating the Influence of Tensile Force on Coupled Vibrations of Rotating Slender Beams

Abstract

Coupledvibrations of twisted rotating slender beam linearly varying channel crosssection under aerodynamic couplings including the effect of tensile force in acentrifugal force field have been studied by Sharma [21]. The special case ofstraight beam (zero twist) is of considerable practical importance and meritsan independent treatment. This paper presents the analysis of this special casewhich was found amenable to a different form of solution resulting in a savingnumerical work involved.
